Title: Method of speed field's electrodiffusion measuring in liquids with natural content of depolarizers
Inventor: WICHTERLE KAMIL ING CSC
IPC: G01P5/08
Filed: 1989-06-22
Abstract: The solution can be used in research of convective processes in liquids, in medical diagnostics, in control of industrial processes for example of anaerobic fermentations and in other situations, when measuring flow velocity brings about an important piece of information. In comparison to laser-doppler anemometry and thermoanemometry the electrodiffusive velocity measuring is mechanically less complicated and more robust, but it is limited to electrically conductive liquids containing depolarizer. The proposed method solves two issues connected with the use of natural depolarizer - their concentration variability and electrode passivation. The principle of the proposed solution consists in the cyclic regeneration of the sensor by means of a voltage pulse and in the stabilisation at current-less state with subsequent repeated measuring of transition currents in potentiostatic mode. When measuring in service water the proposed solution is performed by a gold working electrode, auxiliary zinc electrode, or AKV stainless steel electrode, and concrete voltages and time delays are specified for optimum measuring procedure.<IMAGE>

Patent JP-H0477391-B2 (JP)
IPC: G11B27/30
Filed: 1986-01-13
Abstract: An information recording and reproducing apparatus records and reproduces information on and from an optical recording disk having a sector recording format of frame structure in which data in each sector are divided into a plurality of frames, and a data head identification mark is affixed to the head of each of the frames, so as to prevent propagation of a demodulation error due to failure of word synchronization attributable to pull-out of a PLL during data reproduction. In the apparatus, one frame pulse is generated for each of the frames on the basis of a sector identifier detection signal and a frame data demodulation start signal, and, according to the result of counting the frame pulses, the frame numbers of frame data demodulated and stored in a sector buffer memory are accurately detected. The frame pulse is generated on the basis of the sector identifier detection signal until the data head identification signal is first detected, and, once the data head identification signal is detected, the frame pulse is generated on the basis of the data demodulation start signal. Therefore, even if the data head identification signal of a frame cannot be detected resulting in dropout of data in that frame, the succeeding frame data can be stored at the assigned addresses in the sector buffer memory.

Granted: 2003-12-18
Abstract: The invention relates to a flat heat-sealed bag packaging for a large number of moist tissues or other consumable articles, consisting of a flexible packaging material (1), which has a convenient resealable opening on the opening side (4) and a permanent adhesive coating on the adhesive side (5) which is opposite said opening side (4). The adhesive coating is covered by a protective film (6). Said protective film (6) is removed for use and the packaging is stuck onto a wall or onto another surface which is as stable as possible. The adhesive fixing lends the packaging new stability and rigidity which enables said packaging to be simply opened, the contents to be removed and to be resealed, in particular with one hand; an operation which is otherwise only possible with more complex packaging. To remove, the empty packaging can simply be peeled off the surface. The packaging consists for example of a plastic film, aluminium foil or of a composite material.

Title: Electromagnetic stirring of continuously cast metal
Inventor: BIRAT JEAN PIERRE
IPC: B22D11/12
Filed: 1983-06-15
Granted: 1988-01-21
Abstract: In a continuous-casting method molten steel is continuously introduced into a continuous-casting mold to form therein a strand having a free surface in the mold, a pair of relatively wide faces, and a pair of relatively narrow faces. The mold and the steel therein are continuously cooled to externally solidify the molten-steel strand while leaving same internally molten and the externally solid and internally molten strand is continuously withdrawn from the lower end of the mold. The core of the strand solidifies increasingly as it moves from the mold and terminates downstream of the mold at a pool bottom. At each of a plurality of locations spaced apart about 1 m to 2 m longitudinally along the strand between the mold and the pool bottom a respective magnetic field is formed with the fields passing through the strand from between about 3 m to 7 m beneath the free surface to about 2 m to 6 m from the pool bottom. These fields are displaced transversely of and generally parallel to the side faces of the strand with each field moving opposite to the adjacent field or fields so as to magnetically transversely and oppositely displace respective portions of the molten core of the strand.
